All possible optically active regioisomers of myo-inositol mono- and bisphosphates were synthesized using inositol derivatives suitably protected with various protecting groups (IRns) as key intermediates. A series of procedures including Novozym 435 cata

scyllo-Inositol phosphates, which are among the stereoisomers of myo-inositol phosphate, can have 15 possible regioisomers including three enantiomeric pairs: scyllo-I(1,2)P2, scyllo-I(1,2,4)P3, scyllo-I(1,2,3,4)P4. We her
Facile syntheses of all possible diastereomers of conduritol and various derivatives of inositol stereoisomers in high enantiopurity from myo-inositol

Phosphoinositide-based signaling processes are crucially important in intracellular signal transduction events. Inositol phosphate analogues have been useful in probing the structure-activity relationships between inositol phosphates and biomacromolecules, and in studying biological functions of newly found inositol phosphates. Thus, a systematic and ready access to inositol stereoisomers is highly desirable. And practical and convenient syntheses of conduritols and related compounds are also important because of their biological activities and their synthetic utilities in the preparation of other bioactive molecules. We herein report the first syntheses of all possible diastereomers of conduritol and various derivatives of eight inositol stereoisomers in high enantiopurity from myo-inositol, which involve efficient enzymatic resolution of the intermediates conduritol B and C derivatives, followed by oxidation-reduction or the Mitsunobu reaction, and cis-dihydroxylation in stereo- and regioselective manners.
Enantioselective approach to polyhydroxylated compounds using chiral sulfoxides: Synthesis of enantiomerically pure myo-inositol and pyrrolidine derivatives

A short enantioselective Synthesis of the biologically important myo- inositol derivative I and the pyrrolidine derivative II is described. The molecule 3, a diketo disulfoxide readily made from tartaric acid, is the key intermediate. The sulfinyl group controlled completely the very high stereoselection observed.
